high Tenable Cloud Security Plugin ID 400976

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- hostapd 0.6.7 through 2.5 and wpa_supplicant 0.6.7 through 2.5 do not reject \n and \r characters in
passphrase parameters, which allows remote attackers to cause a denial of service (daemon outage) via a
crafted WPS operation. (CVE-2016-4476)

- wpa_supplicant 0.4.0 through 2.5 does not reject \n and \r characters in passphrase parameters, which
allows local users to trigger arbitrary library loading and consequently gain privileges, or cause a
denial of service (daemon outage), via a crafted (1) SET, (2) SET_CRED, or (3) SET_NETWORK command.
(CVE-2016-4477)
